Thanks to all this high-tech study, scientists have figured out that DVM is fueled by more than just sunlight changes.

多亏了所有些高科技研究，科学家们已经发现 DVM 不仅仅由阳光变化促进的。

Speaking with the American Kennel Club, veterinarian Dr. Laurie S. Coger, DVM, said that munching on soil can be indicative of a dog's emotional state.

兽·科格博士（音译）在接受美国犬业俱乐部 采访时，咀嚼土壤可以表明狗的情绪状态。

Dogs have two types of cones that pick up blue-violet and yellow shades, says Lara Sypniewski, DVM, a professor of small animal medicine at Oklahoma State University.

俄克拉何马州立大学小型物学教授、兽临床生拉腊·西普尼夫斯基称，狗有两种视锥细胞，可以分辨蓝紫色和黄色。

12. For a tiny microscopic organism, that's a huge distance! Remember now, zooplankton can't swim very well, and DVM requires a lot of energy, so there must be an important benefit to this daily up and down commuting.

对于一个小型微生物来，一个很长的距离。要记住，浮游物不能很好的游且昼夜垂直移需要很多能量，所以每日沉沉浮浮的移过程一定有重要的益处。

It's called the diel vertical migration or DVM for short.

它被称为昼夜垂直迁移或简称 DVM。

It turns out that studying DVM could help us unravel our own circadian rhythm, the biological clocks that help our bodies keep time.

事实证明，研究 DVM 可以帮助我们解开自己的昼夜节律，也就帮助我们身体保持时间的生物钟。

Humans have three types of cones, " which enables us to see different shades of red, blue-violet, and green, " says Alison Meindl, DVM, a veterinarian, and professor at Colorado State University.

科罗拉多州立大学教授、兽学博士、兽艾莉森·梅恩德称，人类有三种视锥细胞，“因此我们能够看到不同深浅的红色、蓝紫色和绿色。”
